BUNG FOR CASKS.

Application filed November 30, 1921.

T 0 aZZ whom it may concern:

Be it known that we, ALEXANDER RAD, MIoHAEL MAYER, and LUDWIG VON EGERHAZY, all citizens of Hungary, residing at Budapest, in the Hungarian'Republic, have invented new and useful Improvements in Bungs for Casks, of which the following is a specification.

This invention relates to bungs for casks.

It is well known that the ordinary manner of closing casks is unsatisfactory and is not secure against tampering with the contents of the cask.

Gasks are mostly closed by means of a wooden bung which, in being taken out, produces a deformation of the staves in such a manner that same have to be replaced almost every year.

These objections are obviated by the improved means hereinafter described and which are entirely safe and can be opened at any time, without damaging the cask.

The invention is shown by way of example in the accompanying drawings, in which Figure 1 is a section partly in side elevation of the improved bung for closing the cask; Fig. 2 is a plan of same.

According to this invention, the bung hole of the stave a. receives a metallic sleeve or socket 7) which is screwed into the wood. In this socket is mounted a metallic bung d having a groove at its lower portion for the reception of a packing ring 3. The bung 65 carries locking bolts 9 which project diametrically into a circular groove formed in the inner side of the socket b, said bolts 9 being advanced and withdrawn by a suitable key In order to close the bung hole, the hung at is introduced into the socket b and the key f is then turned so. as to advance the bolts 9 into their locking position, thereby securing the real packing ring 8 in a liquid-tight position.

Serial No. 519,018.

On the top surface of the bung cl is secured a cover-plate 2' turning on a peg it so that, after removal of the key f, said plate can be turned on the peg 71 in such a manner as to cover the key-hole and prevent-dirt enterin the key-hole.

The invention may readily take different forms of construction without exceeding the scope thereof. For example, the metallic socket d may have a smooth peripheral surface that is to say without screw-threads and may then be held in position by any suitable means. Further, the locking bolts g and their locking mechanism may be such as to cause the packing ring 8 to be expanded thereby and thus increase the tightening capacity of same.

We claim 1. A bung for casks comprising a metallic lower end and a packing ring fitted in said groove. A

3. A bung for casks comprising a metallic socket fixed in the stave of the cask, a metallic bung inserted in said socket, means for tightening the bung, locking bolts connected with the bung, a key for operating said bolts, and a plate turning on a peg on top of the bung for closing the key hole.
